Use an Affiner to move them to a common origin and then use a Scaler.
This will scale the spacing but will maintain the resolution, which is defined as the number of rows and columns.
To change resolution you can use a RasterResampler, set to columns and rows.
You have to maintain the aspect ratio though, else you'll warp your image.

Seems like RasterResampler would work: http://docs.safe.com/fme/2019.0/html/FME_Desktop_Documentation/FME_Transformers/Transformers/rasterresampler.htm
The documentation also mentions a whole bunch of other Raster Transformers that can be used for more specific purposes.
